Colt Mark IV Series 70 Gold Cup National Match Semi Automatic Pistol
This engraved handgun was destined to be the 1990 Pistol Trophy, but inclement weather forced the cancellation of the match for the first time in Camp Perry competitive history. SN FN32437
The first match-grade service pistols produced by the Army Ordnance Corps for use at the National Matches were issued at the 1955 National Matches for use by competitors and in the Small Arms Firing School. That first National Match pistol was identical in appearance to an ordinary service pistol except for the substitution of checkered walnut stocks for the regular issue plastic stocks.
Internally, the 1955 National Match pistol's accuracy was improved by the replacement of the service barrel with a National Match barrel, the service barrel bushing with a National Match bushing and the barrel link with a special link. The replacement bushing and link served to return the barrel after recoil more precisely to the same relationship with the slide and sights for each shot. Each year thereafter, additional improvements and modifications have been made to the National Match pistol. In 1956, for example, the service front sight was replaced by one 1/8" wide and the rear sight notch was cut to 1/8".
The 1957 sights were higher (.395 rear and .295 front) and the 1958 sights at .458 and .358 were higher yet. 1961 saw the introduction of an adjustable commercial rear sight in the Micro sight, which was replaced by the Elliason-type rear sight in 1963. While some National Match pistols were sold each year to National Match competitors and to others eligible to purchase from the Director of Civilian Marksmanship, those remaining in government control were generally returned to Springfield Armory each year for rebuild to new specifications. Shooters who purchased these pistols, in many cases, have had them modified to incorporate the latest improvements. Thus, early National Match pistols in their original configuration are relatively rare.
